WEB-PERFECTING PPdNTlNG-MACHWE.

SPECIFICATION forming part of Letters Patent No. 317,740, dated May 12,18:85.

Application filed January 13, 1882.

To all whom it may concern.-

Be it known that I, LUTHER G. GRowELL, a citizen of the United States,residing in the city of Brooklyn, county of Kings, and State of NewYork, have invented certain new and useful Improvements in RotaryWeb-Perfecting Printing-lilachines, fully described and represented inthe following specification and the accompanying drawiu gs, formingapart of the same.

This invention relates to that class of machines which are adapted toprint both sides of a moving web of paper, sever the same into shortlengths or sheets, and then deliver the same as a folded product insuitable form for the carrier or for mailing, and which are knownin theart as rotary web-perfecting printing-machines.

The invention relates more particularly to that class of thesemachinesin which each formcylinder is provided with a plurality ofimmession-cylinders, so that two or more webs can be printedsimultaneously from the same setbf plates or forms.

One part of the invention consists in the combination, with two printingmechanisms set at an angle to each other, of means for leading a web ofpaper to the first mechanism from the side adjacent to the secondmechanism, a web-turner arranged to turn and guide the web from one tothe other, and means for leading the printed web from the secondmechanism upon the side adjacent to the first mechanism.

The invention also includes the combination, with a web-printingmechanism which is arranged to perfect a plurality of webs and deliverthem at the same side of the machine, of a single cutting and foldingmechanism arranged to operate upon both webs.

The invention also embraces various details of construction andcombinations of parts both in the printing and delivery mechanisms, allof which will be hereinafter fully explained, and particularly pointedout in the claims, in connection with the accompanying drawings, inw-hich Figure 1 is a plan view of a mechanism embodying those parts ofthe invention which relate to the printing of the web or webs. Fig. 2 isa sectional elevation of the same, taken upon the line 00 m of Fig. 1.Fig. 3 is a (No model.)

similar view taken upon the line y y of the same figure, showing also inside elevation a modified form of the delivery mechanism. Fig. 4 is asectional elevation of the delivery mechanism, taken upon the line as a:of Fig. 5. Fig. 5 is a sectional elevation of the same, taken upon theline 0000 of Fig. 4. Figs. 6 and 7 are detail views upon an enlargedscale, showing the manner of operating the pins upon the cutting andfolding cylinders. Figs. 8,9, and 10 are similar views, also upon anenlarged scale, showing the pins as operated in a slightly-differentmanner, and illustrating also the operation of the cutting and foldingcylinders in associating sheets. Fig. 11 is a plan view, upon anenlarged scale, of the supplement-introducing mechanism. Fig. 12 is asectional elevation of the modified delivcry apparatus hereinbeforereferred, to, the

same being taken upon the line 2 z of Fig. 3. Fig. 13 illustratesdetails to be hereinafter referred to.

Referring particularly to Figs. 1, 2, and 3, it is to be understood thatthe printing mechanism therein shown consists of two groups ofmechanism. The first of said groups is mounted in suitable bearings atthe left of the machine, as seen in Figs. 1 and 2, and consists ofat'orm-cylinder, 1, and two impressioncylinders, 2 and 3, which arearranged one above the other, the cylinders l and 3 being in a verticalline, while the upperimpressioucylinder, 2, is placed a short distanceto the right of this line, as seen in Fig. 2. This arran gement is madein order to allow space for the introduction and removal of the platesbut it is not absolutely essential, and may be varied as may be founddesirable without departing from the invention. These three cylindersare provided with engaging gears 4 5 6, (see Figs. 1 and 12,) by whichthey are causerl to revolve in unison, motion being communicated to themfrom a bevel-gear, 35, upon the driving-shaft 36 through a bevel-gear,33, upon the shaft of the cylinder 2.

The form-cylinderl is provided with two sets of inking mechanism,consisting of the distributing-rolls 8 9, which are supplied with inkfrom a fountain in any suitable manner, and the form-rolls 10 11, all ofwhich are of the usual construction, and operate to ink the forms in theusual manner.

The second group of printing mechanism is arranged at or substantiallyat right angles to the first group, and also consists, like the first,of one form-cylinder, 31, and two impressioncylinders, 23 32. Thesecylinders are placed in the same relation to each other as the cylindersof the first group, and the form-cylinder 31 is also provided withinking mechanisms similar to those described in connection with thecylinder 1. These cylinders are provided, like the cylinders 1 2 3, withengaging gears, (see Fig. 1,) by which they are caused to rotate inunison, motion being communicated to them from the bevel-gear 35 uponthe driving-cylinder 36 through a bevel-gear, 34, upon the shaft of thecylinder 23. To the printing mechanism thus organized there are led twowebs of paper, 12 13, which are contained in rolls 1415, mounted uponspindles 16 17, which are supported in any suitable manner at the rightof the machine, as seen in Fig. 2. The web 13 from the roll 15 passesover a guide-roll, 19, and thence downward between theimpressioncylinder 2 and the form-cylinder 1, in passing which it isprinted upon one side by the plates upon the cylinder 1, after which'itpasses upward around the cylinder 2, and thence backward toward thepoint of starting, it being printed upon what is now its upper side. Astheweb is led backward toward its point of starting, it is led downwardaround a turnin g-bar, 20, which is arranged obliquely across the pathof the web, as shown in Figs. 1 and 2, so as to be turned at rightangles to its previous path of travel. After passing the turning-bar 20,the web, with its printed side now downward, is led around theimpression-cylinder 23, and between it and the form-cylinder 31, andthence forward above a guide-roll, 37, and across its path of travel inentering the machine.

The turning-bar 20, which, as here shown, consists of a simple bar ofwood or metal, although it may be formed of a plate provided with anoblique turning-edge, is hinged at one end by a ball-and-socket or otheruniversal joint, 22, to a bracket, which is secured to the frame ofthemachine, as shown in Fig. 1, while its opposite end is supported in anadjustable bearing secured to the opposite side of the frame-work. Bythis means the turnercan be swung in any direction, so that it can beset at any desired angle of relation to the cylinders 2 and 23, so astocause the Web to be properly directed fromthe first to the second ofthe groups of printing mechanism.

The adjustable bearing just referred to, in which one end of theturning-bar 20 is supported, consists of acollar, 24, which receives theend of the turning-bar and. is provided with a stem, 28, (see Fig. 13,)which enters a suitable bearing in the bracket 21, where it is securedin position by set-screw 25, passing through the bracket and impingingagainst said stem. By loosening the set-screw 25 and moving the stem 28up or down, the vertical angle of the turning-bar can be adjusted withsaid cylinder and the form-cylinder 1.

relation to the printin g-cylinders. The bracket 21 is secured to theframe of the machine by bolt27, passing through a slot, 29, by whicharrangement the bracktt is capable of being shifted upon the frame ofthe machine so as to adjust the horizontal angle of the turningbar withrelation to the printing-cylinders. The web 12 from the roll 14 is ledinto the machine directly beneath the web 13, and, after passing above aguide'roll, 18, is conducted upward around the impression-cylinder 3 ofthe first group of printing mechanism, and between In passing betweenthese cylinders it is printed upon its upper side in the same manner ashas already been described in connection with the web 13. After beingthus printed, it is led backward toward the roll 14 and downward arounda turning'bar, 41, which is constructed and arranged in precisely thesame manner as has already been described in connection with the bar 20,and by which the web is turned at right angles to its previous path oftravel, and directed to the second group of printing mechanism. Afterleaving the bar 41, the web is led outward between the form andimpression cylinders 31 32, thence down ward around theimpression-cylinder 32, and inward above a guide-roll, 42, and thenceforward across its path of travel in entering the machine.

Referring now particularly to Figs. 4 and 5, the operation of thedelivery mechanism in disposing of the product'of the two webs will bedescribed. The web12, as it reaches the side of the machine, is ledupward around a guide and register roll, 43, thence forward over asecond guide and register roll, 44, onto the face of a longitudinalfolder, 45, while*the web 13, as it arrives at the side of the machine,

is led upward around a guide and register roll, 7

38, thence forward directly above the web 12, over the roll 44, and overa similar roll, 39, onto the face of a longitudinal folder, 40.

It is to be remarked in passing that the rolls 43 38 will in practice hemade adjustable in position, so that the travel of the webs may beproperly regulated to secure accurate registration with the cuttingmechanism, which will be hereinafter described. 1

The longitudinal folders 40 45 may be of the construction shown inUnited States Letters Patent No. 233,997, or of any other approved formwhich is adapted to longitudinally fold a'continuouslymoving web orsheet of material. These longitudinal folders 40 45 are arranged one inadvance of the other, (see Fig. 4,) so that the folded webs 12 13, asthey pass from the surface of their respective folders, are received andfed forward by the single pair of rolls 46 47. The perfected andlongitudinally-folded webs then pass to the transverse cutting andfolding mechanism, which will now be described. This mechanism consistsof two cylinders, as 48 49, which are provided with cutting and foldingdevices, and of a pair of cooperating longitudinally-folded webs.

folding-rolls, as 58 59, (see Fig. 5,) all of which cylinders and rollsare of sutficient length to receive side by side and operate upon thetwo The cylinders 48 49 are geared together, and are driven from thegear 5 of the'form-cylinder 1 through the intermediates 54 55. Thefolding-rolls 46 47 and 58 59 are or may be driven through intermediatesconnecting them with any appropriate one of the before-mentioned gears.These devices thus form a single delivery mechanism capacitated toreceive and dispose of the products of the two printed webs.

Referring now particularly to Figs. 6 to 10, inclusive, it will be seenthat the cylinder 49, which in the case shown is of the same size as theform-cylinder, which may carry circumferentially two duplicate sets offorms, is provided at opposite points of its periphery withcorresponding sets of sheet-holdin g pins 69 70. These pins are pivotedto the ends of arms 71 72, carried by rock-shafts 73 74, journaled inthe ends of the cylinder, and are arranged so as to be moved in and outthrough holes in the surface of the cylinder. The rockshafts 73 74 areprovided with springs which normally hold them in such position that thepins 69 70 are drawn within the cylinder and carry rock-arms 79 75,through which the shafts are rocked to protrude the pins. When,therefore, the leading ends of the webs, after passing between the rolls46 47, reach the bite of cylinders 48 49, the revolution of cylinder 49will, as shown in Fig. 6, bring the stud or roll 76 of the arm 75,carried by the rock-shaft 74, into contact with the stationary cam 77,thereby rocking the shaft 74, and causing the pins 70 to protrude beyondthe surface of the cylinder and impale the leading ends of the webs, asshown in Fig. 7. The webs thus impaled upon the pins 70 will be carriedaround upon the surface of cylinder 49, as shown in Fig. 8, until thecylinder has made one-half a revolution, at which time the knife 65,carried by the cylinder 48, coacting with recess 81 in cylinder 49,severs the webs. At the same time or immediately before the webs aresevered the stud or roll 80 of rock-arm 79, carried by rock-shaft 73,comes into contact with the stationary cam 77, thereby causing the pins69 to protrude and impale the webs just in the rear of the point ofseverance, as shown in Fig. 8. Shortly after the webs are severed by theblade the stud or roll 76 will pass off the cam 77, as in Fig. 9, thusallowing the spring heretofore referred to to retract the pins andrelease the sheets, which are immediately folded between the rolls 58 59by the rotating folding-blade 78. The freshly-cut ends of the webs areheld by the pins 69 and carried around onehalf a revolution with thecylinder 49, and are then released in like manner and folded betweenrolls 58 59 by the rotating folding-blade 82, the blade 65 and pins 70having in the meantime again come into operative position with respectto the webs to repeat the operation just described.

The rotating folding-blades 78 82 are constructed and operated in theusual manner and require no specific description 5 but it may be statedthat any of the well-known modes of operating folding-blades in arotating carrier may be employed.

It is to be remarked that after being folded between the rolls 58 59 thesheets may pass to other folding or to folding and wrapping mechanisms,to be still further manipulated; or they may pass onto a fly and bepiled upon a table or fly-board.

In the operation just described it will be observed that the mechanismproduces and delivers twice-folded four complete papers at eachrevolution of the formcylinders, and conse-' quently that each papercontains matter equal to one-half the circumferential capacity of saidcylinders. If it is desired to deliver these papers in pairs, it may beaccomplished as follows: The cylinder 48 is provided with a set ofsheet-holding pins, 62, located just in the rear of the knife 65. Thesepins are pivoted .to the arms 63 of a rock-shaft, 64, journaled in theends of the cylinder, and are adapted, like pins 69 70, to move in andout in holes in the surface of the cylinder. The rock-shaft 64 isprovided with a spring, the tendency of which is to hold the shaft insuch a position that the pins will project beyond the surface of thecylinder. One end of the rockshaft 64 is provided with a rock-arm, 68,carrying a stud or roll, 67, which at each alternate revolution of thecylinder 48 comes in contact with an adjustable cam, 66, carried uponthe end of cylinder 49. When the papers are to be delivered singly, asalready explained, the arm 68 is forced inward, so as to draw the pins62 inside the cylinder 48 and make them inoperative, and is theresecured in any convenient manner. When the papers are to be delivered inpairs, the arm 68 is released, so that the pins 62 can come intooperative position, and one set of the pins upon the cylinder 49 (theset 69, as shown in Figs. 9 and 10) is rendered inoperative. This may bedone by removing the arm 79 from the rockshaft, or by turning it toanother position upon its shaft and then securing it so that it will notcome in contact with cam 77.

The parts being thus arranged, the operation will be as follows: Thepins 69 being inoperative, the leading ends of the webs will be impaledupon the projecting pins 62, as in Fig. 9, and carried around uponcylinder 48 until said cylinder has made one full revolution, at whichtime the knife 65 will sever the webs and the freshly-cut ends, and theends held by pins 62 will be brought together, as shown in Fig. 10. Justat or a trifle before this time the cam 66 is brought into engagementwith the stud or roll 67 of arm 68, and the shaft 64 is rocked so as towithdraw the pins 62, as in Fig. 6. At the same time that the pins 62are withdrawn the stud or roll 76 of arm 75 comesinto contact with cam77, and the pins 70 are projected so as to impale the leading ends ofboth the webs and the severed sheets and carry them around upon thesurface of cylinder 49. When they have been thus carried one-half arevolution, the knife 65 will again sever the webs, and, the cam 66being absent, the pins 62 will project, so as to impale the freshly'cutends of the webs and carry them around on cylinder 48, as shown in Fig.9. The pairs of papers thus associated on the cylinder 49 will bereleased from the pins 70 and folded between the rolls 58 59 by blade 78at the proper time, and in the manner already explained, and theoperation will then be repeated. In Fig. 8 the cam 66 is shown as placedso as to co-operate with the pins 69. This, however, is immaterial, asthe cam may be placed so as to cooperate with either they pins 69 or 70,the other set being rendered idle when sheets are to be associated. Whenthe pins 62 are retracted to release the leading end of the sheets fromcylinder 48, it is necessary that they should be prevented fromprotruding beyond the surface of the cylinder again until they have beencarried sufficiently far from the surface of cylinder 49 to preventtheir points from striking the paper upon that cylinder. In theconstruction shown in Figs.v 6 and 7 this is accomplished by astationary cam, 83, within whichthe stud or roll 67 is forced by the cam66, and inside of which it must travel, and which thus holds the pins 621n their retracted position until nearly a Whole revolution of thecylinder 48 has been completed. During that revolution of the cylinder48, when the pins 62 are required to protrude,the stud or roll 67 passesoutside the cam 83, it not having been acted upon at the commencement ofthe revolution by the cam 66. The cam 83 may be dispensed with and thesame result accomplished by an elongation of the cam 66, as shown inFigs. 8, 9, and 10. If it is desired that the two products made at eachrevolution of the form-cylinders shall, instead of being duplicates,contain different matter, and thus combine to makea single product, theform-cylinders may be provided with appropriate plates or sets ofplates. In that case each sheet of the two pairs which will beassociated upon cylinder 49, in the manner ust explained, willconstitute one-half of a single product,in stead of eachin itselfforming a single or complete product. The number of plates carried uponthe form-cylinders is of course immaterial, so long as they are dividedinto two equal sets, each occupying onehalf the circumferential extentof the cylinder. The columns of matter may also be arranged to extendaround or lengthwise of the cylinder,

according to the style of product which it is desired to produce. Itwill, however, be found most desirable, it is thought, to use fourplates upon each form-cylinder-two in length and two incircumference-and to arrange the columns of matter so that they willextend cireumferentially of the cylinder. When the plates are thusarranged, and the second pair of plates are duplicates of the first, theproduct will be four four-page papers at each revolution, such papersbeing longitudinally folded upon the line between thepages, and theneither singly or in pairs folded transversely. When the plates are thusarranged and the matter upon the plates or sets of plates is different,the product will be two eight-page papers at each revolution, suchpapers being composed each of two four-page sheets, which are foldedlongitudinally between the pages and afterward associated as uponcylinder 49, and folded transversely together. The four-page sheetscomposing these products may be attached to each other by a line ofpaste placed contiguous to thelongitudinal fold-lines. Such line ofpaste can be readily applied by pastingdisks running in contact withcylinder 48. These disks should be made intermittent in their action, sothat paste will not be applied to the surface of cylinder 48 at thetimes when there are no sheets upon its surface.

It has now been shown how the machine described can at option be made toproduce either a four-page or an eight-page product, the pages being thesame size in both cases,

or, in other words, a product containingmat-- ter equal to one-half thecapacity of the formcylinders, or a product containing matter equal tothe full capacity of said cylinders. If, however, it should be desiredto construct a machine of this class capacitated to produce either afour-page, a six-page, an eight-page, or a twelve-page product, thepages being of the same size in all cases, it can readily be done bymaking the form and impression cylinders one half longer, which willcapacitate the form-cylinders to carry two additional plates or pages ofprinting-surface each. When a four or an eight page paper is to beproduced, the number and arrangement of the plates will be the same asalready described, the plates covering only two-thirds the length of thecylinders, and the webs of course being of corresponding width. When,however, it is desired to produce a six-page paper, the two additionalplates will be placed upon each form-cylinder, and webs of correspondingwidth will be used. As the perfected webs l2 and 13 advance toward thedelivery mechanism and pass over their guide-rolls 37 42, slitters, as84, (see Fig. 11,) are arranged to split the wels into two parts, onepart being one-half the width of the other. As only the web 13 is shownin Fig. 1], its wider part is numbered and its narrower part todistinguish it in its further manipulation, it being understood that web12 is similarly operated upon. Each narrow portion, as is carried underand around sets of parallel turnerbars, as 85 86, by which it istransferred laterally and associated with the wider portion, f},

so as to lie between the plies of the latter when it is longitudinallyfolded by the folder,

as 40, thus making the sections severed by the blade consist of sixinstead of four pages, which six-page product can be delivered eithersingly or in pairs, as already described in connection with thefour-page product.

When it is desired to produce a twelvepage product, the additionalplates upon the form-cylinders will contain different matter, and twosix-page products will be associated and delivered in the same manner astwo fourpage products are associated and delivered, as has already beendescribed.

It is to be remarked that the narrow or onethird inset portions of thewebs may be secured in place by a line of paste laid along the centersof the wider or two-thirds portions before the same are folded. Such aline of paste may be applied by any well-known device.

The turners 86, of which there will be two sets-one for each web-will belocated between the guide-rolls 37 38 and 42 43, respectively, andshould be made adjustable, as shown in Fig. 11, in order to secure theaccurate registration of the printed matter upon the two portions of thewebs. To provide for this adjustment of the turner-bars, their ends aresupported in collars 88, which are swiv eled to the slotted brackets 87,secured to the frame of the machine by set-screws 89. The properregistration of the edges of the two portions of the webs is secured byadjusting the turners to the proper angle with relation to the webs, andtheir proper registration in the direction of their travel is effectedby adjusting the bars to the proper distance from each other. Thecollars 88 are made capable of sliding along the bars 85 86, so as topermit this adjustment.

If it is desired to deliver as a product two or more sheets foldedtogether, the primary fold being transverse to the run of the paperthrough the machine, the webs may be split longitudinally just before orduring the passage over the longitudinal folders. This can be wellaccomplished by slitters, such as shown at X in Fig. 12. These slittersshould be arranged so as to be thrown out of operative position whentheir use is not required. It will be readily seen that when the websare thus split in passing the folders 40 45 these folders become merelyweb-associatin g devices, and cease to be longitudinal foldingmechanisms.

In order to insure that the impressions made by the second form-cylindershall register accurately with theimpressions made by the first, thewebs, after receiving the first impression and before they reach theturners 20 41, pass over fixed guide-rolls, as 91, (see Fig. 2,) andunder adjustable guide-rolls, as 90. By adj usting rolls up or down, thedistance traveled by the webs between the cylinders can be varied so asto bring the impressions upon the opposite sides of the sheetinto properregister. The rolls 90 may be secured in their adjusted positions by ascrew, or by any other suitable means. In the drawings the web 12 aloneis shown as supplied with. this register-regulating device; but it is tobe understood that the web 13 is also to be provided with similardevices. The distance traveled by the webs after leaving the secondgroup of printing devices, and before reaching the longitudinal folders40 45, may be varied so as to bring them into proper register with thesevering devices 65 81 by the adjustment of the rolls 38 39 43 44.

In Figs. 3 and 12 there is shown a modified form of delivery mechanism,in which the longitudinal folders 40 45, instead of being located in thesame plane and arranged so that both co-operate with the same pair offolding, cutting, and associating cylinders, are arranged one above theother, and provided with independent co-operating devices. The devicesthus designated form two independent sets of delivery mechanisms, eachof which delivers the product of one of the webs, the web 13 beingoperated upon by themechanisms of cylinders 48 49, and its productdelivered between the rolls 58 59, and the web 12 by the mechanisms ofcylinders 52 53, and its productdelivered bet-ween the rolls 60 61. Thecylinders 52 53 are geared together, and are driven by gear 5 upon theshaft of form-cylinder 1 through the intermediate gear, 54. Thecylinders 48 49 are also geared together, and are driven throughintermediate 55, which engages with gears 56 57 upon the shafts ofcylinders 52 and 49.

The folding-rolls 46 47, 50 51, 58 59, and 60 61 are or may be driventhrough intermediates connecting them with any appropriate one of thebefore-mentioned gears. These delivery mechanisms are exactly the samein their construction and operation as that already described, exceptthat the rolls and cylinders are only of one-half the length.

It will be observed that the method herein described of printing the twowebs and leading them to the delivery mechanism causes both webs tocontain the same printed matter upon their upper surfaces, and that,therefore,

.when both webs are operated upon by the same delivery mechanism, as inFigs. 4 and 5, the products of both will be delivered in the same order,or with the same matter upon the outside. By the mechanisms shown inFigs. 3 and 12, however, the result will be difierent. The webs beingfolded in opposite directions, the matter which is on the inside of theproduct of one web will be on the outside of the product of the other.

It is to be remarked that it is not necessary that the two groups ofprinting mechanisms should be placed at right angles to each other. Theangle may be either considerably more or less than a right angle, itbeing only necessary that the angle should be such that the webs can beconducted from one to the other by the use of a turner having a singleturning edge or surface.

The impression-cylinders which act upon one or both of the webs shouldbe made adjustable, so that they can be withdrawn from contact with theform-cylinders in case it should be desired to use the machine to printfrom one web only.

The gears 33 34, as will be observed, are secured to the shafts of theimpression-cylinders 2 23; but it is to be remarked that it will usuallybe found preferable to place the gear 33 upon the shaft of theform-cylinder 1 and the gear 34 upon the shaft of the form cylinder 31.

A mechanism of the construction herein set forth possesses greatadvantages over those of the same general character heretofore used, inthat both webs of paper are led from the same side of the machine, thusmakingit easy for an operative to attend to both rolls at the same time.The product of both Webs is also delivered at the same or substantiallythe same point, and in close proximity to the rolls from which the websare drawn, thus making it possible for the same operative to attend toboth the feeding of the webs and the removing of the product. This novelarrangement of the various parts also renders the machine very much lesscumbersome than those of an. equal capacity as heretofore constructed.

As will readily be seen, any ordinary form of delivery mechanism may besubstituted for that here shown and used in connection with the printingmechanism herein described, and this delivery mechanism may be used inconnection with other forms of printing mechanism.

Although the web-associating mechanism combined with web-severing andsheet-associating mechanism is herein shown, the same is not hereinclaimed, but is claimed in my application filed June 22, 1883, No.98,940; neither are the duplicate delivery mechanisms shown in Figs. 3and 12 herein claimed, as these mechanisms will form the subject-matterof afuture application for Letters Patent.

What I claim is- 1. The combination, with two printing mechanisms set atan angle to each other, of means for leading a web of paper to the firstmechanism from the side adjacent to the second mechanism, a web-turncrarranged to turn and guide the web from one to the other, and means forleading the printed web from the second mechanism upon the side adjacentto the first mechanism, all substantially as described.

2.
